I am in the middle of doing updates, as I would any week. iTunes has been telling me to update for a few days. I went to the itunes website to get the file today. I downloaded it no problem. I started the install with how I wanted installed and walked away for a few minutes while it updated. When I came back the attached picture had popped up on my screen. I have NEVER had it happen before and I don't know what to select so it's still sitting open on my screen. I only use iTunes to connect my iPod nano 3G (small fat rectangle, not the long rectanlge one cir. 2007) to add new songs. No other device is connected to iTunes. I've never before had problems with updates for iTunes. Please advise me what to do.
